I've decided to take action against the dreaded marine ich. Yesterday my 3 blue reef chromis showed plenty of white spots which I presume to be ich. The hippo tang that my neighbor donated is the known cause and has had signs of it on and off. I ordered a sponge filter to use as biological filtration for a 25-30 gallon tub I have. Hypo salinity is going to be the way I go. is this enough room for 1 tang, 3 chromis, 1 clown, 1 valentini puffer? I will put sponge filter in sump for 4 weeks to get bio media into it. After this, addition of PVC
will go into tub and ill be good to go, I hope. If there's anything I'm missing please give input because I want to end this the first time. What is the schedule for treating ich with hyposalinity like?Thanks for everyone's advice.
